Patent JP-H0465837-A (JP)
Title: Field effect transistor
Inventor: TOKUYASU TAKASHI
IPC: H01L21/338
Filed: 1990-07-06
Abstract: PURPOSE:To prevent from insulation destruction of a gate electrode by making shorter the minimum space between a source pad portion and a gate pad portion apart from each other than the space between a source electrode and a gate electrode apart from each other. CONSTITUTION:A drain electrode 3, a source electrode 4, and a gate electrode 5 are connected respectively to a drain pad portion 6 which is a bonding pad portion, a source pad portion 7, and a gate pad portion 8. These pad portions are formed on the portion where an activating layer 2 is not formed. An acute angle portion 9 is set as part of the source pad portion 7. The space Lp between the tip of the acute angle portion and the source pad portion 7 is 0.5mum. This space is set to shorter than that of the space Lgs (0.8mum) between the source electrode 4 and the gate electrode 5. When a high voltage is impressed between the gate electrode and the source electrode of the field effect transistor, an electric current flows via the acute angle portion 9 between the source pad portion 7 and the gate pad portion 8, before an electric current flows between the source electrode 4 and the gate electrode 5. Therefore, no damage will be given to the transistor due to flow of a large current in he active layer 2 which is the operating part of the field effect transistor.

Title: Manufacture of integrated memory cell
Inventor: PIEERU JIYOO
IPC: H01L27/115
Filed: 1989-07-13
Abstract: PURPOSE: To improve the degree of integration of a memory by executing a process for insulating floating grids formed along a first direction in the lateral direction and the successive process for actually forming the floating grids. CONSTITUTION: A memory is provided with a matrix of memory points which are electrically insulated from each other and each memory point is provided with a drain 6, a source, and a floating grid 350. The floating grid 350 of each memory point is separated in the lateral direction and insulated from other one or two floating grids 350 along a first direction. The insulation of the grid 350 in the X-direction is performed by forming a spacer 320 having a desired thickness X3 before the floating grid 350 is actually formed. Therefore, the size of the memory can be reduced by shortening the distance between the floating grids 350 of two memory points and the degree of integration of the memory can be improved.

In this case, the P type impurity region 23 is shaped so that its impurity concentration is made lower than the P<+> impurity region 24 and it coats the P<+> impurity region 24. Accordingly, dielectric resistance is increased because a PN junction is formed to regions 26, 27 and the impurity concentration of the P type impurity region 23 is low.
